New Manual: CCR Cave Diving “Almost” Simplified
I realized as a CCR cave instructor that there is a void of information available to the new CCR cave diver specifically in regards to dive planning. I feel that it is important for a student to be armed with information before attending a class, as this will increase learning, retention, and overall safety. My latest book CCR Cave Diving “Almost” Simplified is my attempt to help the upcoming CCR cave diver get the most out of their class. Like all my previous “CCR Simplified” manuals the goal is to put in simple words how to use the rebreather in the particular application in this case the cave environment. The book will be released at the BTS show March 25th. It is a 160 page full color richly illustrated high quality manual. The cost is 79.95. There will be a limited supply at the BTS show for the show special price of 70.00.
